AS ADVERTISED HARD TO BELIVE BUYING RACE CAR PARTS FROM A TRAILER DEALER



by:

Works better than expected. Put this on a Cat 3054T for my Morbark model 13 chipper. Stock fan was about $300.00 No complaints after one year of use.



by:

Just installed this fan on a cj5, and wow this thing moves some air, at idle and all through the rpm range. I would definitely buy this again for other projects.

Ask the Experts about this Derale Radiator Fans



  • Could Derale 20" Rigid, Steel-Blade Race Fan Push and Pull Air
    In theory yes, the Derale 20" Rigid, Steel-Blade Race Fan # D17320 could spin either direction and push or pull air. But since this is designed to mount to a pulley on an engine you wouldn't be able to get it to push air through a radiator.

  • Electric Fan Setup Recommendation for 1996 Dodge Ram with 5.9 Liter Cummins
    For a fan setup that would work well for your 22-1/2 inch wide setup the Derale 22-1/2" Dual, High-Output Electric Radiator Fan w/ Aluminum Shroud # D16830 would be a fantastic option assuming it would fit for a vehicle like your 1996 Dodge Ram with 5.9 liter Cummins that would need some serious cooling power. This setup has a shroud and dual fan setup that can move up to 3,750 CFM which would do a great job cooling the radiator. The fan diameters are 11 inches. Overall dimensions of the...

  • Does Derale Race Fan # D17320 Move More Air Than Derale Flex Fan # D17019
    The two Derale fans referenced, their 20-inch Race Fan # D17320 and their 19-inch Flex Fan # D17019, will offer similar performance at lower RPMs, but at higher RPMs the Race Fan will deliver more air volume. As a result it will also put somewhat more drag on the motor. This is because the race fan is rigid and its blades maintain their profile at all speeds, while the flex fan blades are designed to flatten out at high RPMs to allow the air flow from the vehicles speed to provide much...

  • Will the Derale Radiator Race Fan # D17420 Replace the Factory Fan in a 1988 Ford F-250
    The Derale 20 Inch Race Fan, # D17420, has a 19-7/8 inch diameter so it will fit within your 22 inch shroud. One thing to keep in mind with this fan is that it is a race fan which means it will require you to remove your fan clutch as well. It is designed to pull more air as your engines RPMs increase and not to be regulated by a clutch. Removing the factory clutch will effect the length of the spacer that you need. Once you have the clutch removed, you will want to measure from the water...

  • Recommendation for a 1997 Dodge Ram 3500 Diesel and Mounting a Derale 20 Rigid Belt Driven Fan
    According to my contacts at Derale the 20 inch Rigid Steel Blade Race Fan # D17320 can not be mounted to a fan clutch, it is considered a rigid mounting system. This fan is considered a standard rotation, has a maximum rpm rating for up to 8,000 rpm. However, if you would like to consider a fan that will mount to your fan clutch, then you would need the # D17120. This style of fan would mount to your existing fan clutch, and would not need a spacer for mounting. It is also a standard rotation...

  • Will Electric Fans be Effective for 2002 Dodge Ram
    An electric fan will absolutely be able to keep up and is going to be a really good benefit for when you are towing with your 2002 Dodge Ram 2500. You will want to get one that has a solid cubic feet per minute (CFM), and I recommend the Derale 16" Dyno-Cool Curved-Blade Electric Fan - 1,980 CFM # D18916. This is the best option because it is a great value, providing you with plenty of cooling power for the price. It can be used as a pusher or puller and you just need to make sure you...
